[Moose-dev] Evaluating scripts within Pillar

Hi! I am now digging into Pillar. My goal is to be able to insert Roassal script and having it executed. Scripts provided within [[[ ]]] may be evaluated using the variable ‘eval=true’. Here is an example: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= PRHTMLWriter defaultConfigurations anyOne inputString: '100 factorial = [[[eval=true stream nextPutAll: 100 factorial asString ]]]'; outputFile: 'myFirstPillarExport.html' asFileReference; export -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= ‘stream’ is a hardcoded variable name which represents the stream on which you have to write your result. What you write in stream is pillar-friendly. This means you can write something like: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= PRHTMLWriter defaultConfigurations anyOne inputString: '100 factorial = [[[eval=true stream nextPutAll: ''""'', 100 factorial asString, ''""'' ]]]'; outputFile: 'myFirstPillarExport.html' asFileReference; export -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= I have tried to insert some Roassal visualization, and it works pretty well. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= PRHTMLWriter defaultConfigurations anyOne inputString: ' !!Example of a factorial 50 factorial = [[[eval=true stream nextPutAll: ''""'', 100 factorial asString, ''""''. ]]] !!Some Roassal visualizations Here is a small Mondrian example [[[eval=true b := RTMondrian new. b nodes: (1 to: 100). b layout grid. b build. aView := b view. RTHTML5Exporter new insert: aView named: ''Roassal test'' inPillarStream: stream ]]] Another example with Grapher this time: [[[eval=true b := RTGrapher new. b extent: 300 @ 200. ds := RTStackedDataSet new. ds interaction popupText. ds barShape width: 10. ds points: #(4 5 1 -2 5 6). b add: ds. "b axisX noLabel; noTick. " b build. RTHTML5Exporter new insert: b view named: ''A Graph'' inPillarStream: stream ]]] '; outputFile: 'myFirstPillarExport.html' asFileReference; export -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Pillar is very well done!
